Customer Value Translation: ±0.1% repeatability means you can scale production from prototype to high-volume manufacturing without worrying about part-to-part variation. Every sensor housing you receive will match the approved sample, eliminating field failures due to dimensional drift.
Quality Inspection Equipment
Ansix utilizes CMM (Coordinate Measuring Machines) and Optical Imaging Systems for comprehensive quality verification. Every mold undergoes a full dimensional report before leaving the shop, with Critical-to-Quality dimensions maintained at CPK ≥ 1.33. For sensor applications, this statistical process control ensures that critical sealing surfaces and threaded inserts remain within specification across millions of production cycles.
Customer Value Translation: CPK ≥ 1.33 means you can trust that your sensor components will assemble correctly every time, reducing line rejections and field returns. This statistical guarantee translates directly to lower total cost of ownership.

2344 / 8407 / H13 48-52 High hot hardness at 550-600°C, excellent thermal fatigue resistance PPS+40%GF, PEEK sensor housings exposed to high temperatures
NAK80 37-43 Super mirror polish, excellent EDM machinability High-gloss cosmetic surfaces, fine-textured finishes
SKD11 / DC53 58-62 High wear resistance, high compression strength Wear inserts, sliders, shear edges for abrasive filled materials
M340 / 4Cr13 / 9Cr18 48-53 Stainless martensitic, excellent corrosion resistance FDA-grade applications, acidic environments
P20 28-32 Good machinability, cost-effective Mold bases, support plates
For glass-reinforced materials such as PA6+40%GF or PBT, Ansix specifies SKD61 (HRC 52-56) cavity steel to withstand the abrasive wear. For high-temperature engineering resins such as PPS or PEEK, 8407 steel delivers thermal fatigue resistance that keeps production running longer with fewer maintenance stops.
Every material selection is documented in a formal steel certification, accompanied by the full heat-treatment curve for complete traceability.
Customer Value Translation: For level sensor components exposed to aggressive chemicals or temperature extremes, proper steel selection means the mold maintains critical dimensions across its lifetime. Ansix guarantees 500,000 shots for glass-reinforced materials and 1,000,000 shots for standard plastics—directly reducing your per-part tooling amortization cost.
Achievable Tolerances
Component Type Achievable Tolerance
Standard structural parts ±0.05mm
Precision gears / medical components ±0.005mm
Mold Types and Capabilities
Ansix manufactures a comprehensive range of mold types:
Hot runner systems — reducing material waste and improving cycle efficiency
Multi-cavity molds — up to 48 cavities for high-volume production
Two-shot / multi-material molds — for overmolding seals onto sensor housings
High-gloss molds — Ra < 0.05μm for transparent or optical applications
Insert molding — embedding metal inserts or electronic components directly into the sensor housing
Gate and Runner System Optimization
Ansix engineers utilize Autodesk Moldflow simulation software to create a digital twin of the mold and the plastic flow process. The simulation predicts how molten plastic fills the cavity, enabling engineers to:
Identify and eliminate weld lines, air traps, and sink marks before production begins
Optimize gate positions and runner systems to ensure balanced filling and minimize material waste
Predict fill patterns and optimize gate placement to ensure balanced flow across complex geometries
Customer Value Translation: For level sensor housings with complex internal geometries or multiple sealing features, this upfront simulation eliminates the need for expensive mold revisions. Ansix typically reduces physical prototyping costs and time by over 50% through digital validation.
Lead Time Standards
Mold Complexity Standard Lead Time Expedited (with validation preserved)
Simple molds 10 days —
Medium complexity 25-45 days 20 days
Part Three: Injection Molding Process Control — Eliminating Quality Anxiety
Process Standardization and MES Integration
All injection molding machines are connected to Ansix's Manufacturing Execution System (MES). Every processing parameter—melt temperature profile, injection pressure, holding pressure, injection speed, screw rotation speed, cooling time, mold temperature, and back pressure—is locked into the system. Only authorized engineers can adjust parameters, ensuring complete process consistency.
Customer Value Translation: This eliminates the risk of unauthorized operator adjustments causing dimensional drift or cosmetic defects. When you approve a sample, you are approving a locked, repeatable process—not a one-time lucky shot.
Dimensional Stability Control
Ansix maintains mold temperature with multi-zone controllers that keep core-cavity temperature differences within 2°C, directly minimizing post-mold warpage and ovality. For demanding sensor applications, Ansix embeds real-time cavity pressure sensors that feed closed-loop process corrections during every shot, delivering long-term dimensional stability even when resin lots vary.
Customer Value Translation: For sensor housings where sealing surfaces or snap-fit features must remain within tight tolerances, this temperature control means your components fit together correctly every time. Ansix demonstrates key hole spacing variation ≤ 0.02mm across three consecutive production batches—ensuring assembly line compatibility.
Surface Finish and Appearance Grades
Ansix achieves surface finishes appropriate to application requirements:
Transparent parts: No bubbles, no flow marks
Plated parts: No gas marks
High-gloss parts: Surface roughness Ra ≤ 0.2μm
Optical-grade surfaces: Ra < 0.05μm
Customer Value Translation: For level sensors with optical windows or where aesthetics matter, you receive cosmetically perfect parts without costly secondary finishing operations.
